Abstract (en)
[origin: WO0007643A1] This invention is an apparatus for non-invasive flow indication through a rotary pump. The apparatus includes a blood pump (12) adapted for implantation into a patient. The blood pump (12) has a moving mechanism (14) which contacts blood, and imparts energy to the blood to move the blood in the patient at a desired flow rate. The apparatus includes a mechanism (16) for causing the moving mechanism to move the blood. The causing mechanism (16) is engaged with the moving mechanism. The causing mechanism receives energy to power the causing mechanism. The apparatus comprises a non-sensor flow indicator (18) connected to the blood pump to identify the flow of blood through the pump based only on an energy balance between the energy imparted to the blood by the moving mechanism, and the energy received by the causing mechanism. A method for determining blood flow in a patient is also included.
